Problems solved by technology

However, stoppers do not provide a hermetic seal which is necessary in some instances to ensure sterility.
These closures are convenient for periodically accessing the contents of the container, but also do not provide a hermetic seal.
However, these barriers cannot reseal the open top of the container after the initial opening.

Embodiment Construction

[0021]Referring to the drawings in which the like reference characters refer to like parts throughout the several views thereof, FIG. 1 illustrates closure assembly 70 that is used for hermetically sealing and subsequently resealing a container 12 (FIG. 8).

[0022]Container 12 as shown in FIGS. 7 and 8, includes a closed bottom 17, an open top at the opposite end 14 of the closed bottom 17, and a cylindrical side wall 16 extending therebetween defining an interior 19. Located on the outer surface of side wall 16 in proximity to open top 14 are external screw threads for engagement with closure assembly 70.

[0023]Closure assembly 70 includes a top ring assembly 20 and bottom ring 50 as shown in FIGS. 1 and 5. As more fully shown in FIGS. 2 and 3, the top ring assembly 20 is fabricated from three parts: a molded plastic mounting ring 21, a septum 31 and a barrier 41.

[0024]The molded plastic mounting ring 21 is generally an annular member including an annular bottom wall 22 having opposed...

Abstract

A closure assembly is provided for a specimen collection container. The closure assembly includes a bottom ring and top ring assembly. The bottom ring is removably attachable to the open end of the container. The top ring assembly, which is removably attached to the bottom ring, includes a mounting ring and a pierceable, resealable septum that closes the bottom ring and permits pierceable instrument access therethrough. The container interior can also be accessed by the removal of the bottom ring from the open end of the container or by the removal of the top assembly from the bottom ring.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a two piece closure assembly for containers that allows for sample purity while enabling direct access to a sample by diagnostic instrument probes.[0003]2. Description of Relevant Art[0004]Tubes, containers and other collection devices include an open top having a closure that can be removed or opened to access the interior of the container.[0005]Some closures comprise an elastomeric stopper that can be urged into the open top of the container to provide a liquid-tight seal. The stopper can be removed to access the interior of the container and then can be replaced in the opening to reseal the container. The stopper provides a liquid tight seal both before the initial opening of the container and during any reclosure of the container. However, stoppers do not provide a hermetic seal which is necessary in some instances to ensure sterility.[0006]Other closures include structure for thread...
